Using different ball mills as examples, it has been shown that, on the basis of the theory of glancing collision of rigid bodies, the theoretical calculation of t –P–T conditions and the kinetics of mechanochemical processes are possible for the reactors that are intended to perform different physicochemical processes ...

Ball Milling Pretreatment of Corn Stover for Enhancing …

Indeed, ball milling pretreatment is a high-energy-consumption processing, though wet mill mode can save energy to some extent. However, ball milling is a definitely effective process for reducing particle size and disrupting the structure of cellulose fiber bundles, and thus reduces the crystallinity of the cellulose to enhance enzymatic efficiency, and it can be carried out at ambient ...

Conclusion. The effect of ball-milling MgH 2 with and without additives under different gases (Ar, H 2) was surveyed. MgH 2, pre-milled for 20 h under either 10 bar of hydrogen or 1 bar of argon was milled for an extra 2 h with 1 mol% TTIP, Nb 2 O 5 and C 60, also under either H 2 or Ar. The kinetics of absorption and desorption of the composite samples was investigated by thermal desorption ...
